Can I rely on my own DNS server in case of a global DNS blackout?

On March 31st 2012, Anonymous plan to take down the 13 root DNS servers that power the Internet: http://pastebin.com/NKbnh8q8

... and I don't want to even notice if it actually happens.

Assuming what they are trying to do is feasable:

  1. Are there any DNS servers that won't be affected that I can use?
  2. If not, is it possible to create a non-expiring cache of all DNS records on a local machine?
  3. If so, how would I go about doing this?

Of course, DNS changes wouldn't be reflected and TTL would have to be ignored; but that is better than all DNS lookups just timing out.

Having a cache of all DNS records is not feasible. Setting up your own root server on the other hand is! ICANN provides the root zone file here: http://www.internic.net/zones/root.zone

So just set up your own root server, point your DNS servers to it and you should not notice anything.


For Windows there was a program called Treewalkdns that acted as a personal caching dns server. It seems to have dropped out of site but it's probably available somewhere on the web.

There is a Linux program called PDNSD that addresses your requirements: http://members.home.nl/p.a.rombouts/pdnsd/index.html#aboutpdnsd
